Loading default XSLTForms subform on body onload event - xsltforms

I'm trying to use subforms and I had a problem: I saw the example provided in the oficcial XSLTForms but in that case the elements that load/unload the forms are always in the "main form" and, in my case, I need them to desappear, because I'm trying to build something like a wizard, So the first subform must desappear when the user press "Next" and then subform2 is loaded, and so on. This presents two problems:
1) If I include the first subform elements in the "main page", when I press the trigger the elements of subform1 are never unloaded. The other subforms do it, but that initial one is treated as part of the structure that never changes... And I really need to desappear. SO I think I have to put all the content of subform1 outside, in a separate xml and load it in the same way as the other subforms, but there is another problem:
2) I need it be loaded by default, and I tryed to put a load element directly in the main form body, but it didn't work.
I "patched it" temporally with a trigger in the main form, which loads the firms subform, but it is so... ugly, and I still have the same problem: I can navigate through subforms but that initial trigger never dissapears... So, any idea will be welcome! Thanks in advance!

<xf:model xmlns="" >
<xf:action ev:event="xforms-ready">
<xf:load show="embed" targetid="subform" resource="FirstSubform.xml"/>
</xf:action>
</xf:model>

Link directly to a notebook page in a view

I have an view that extends the current project view, where we add multiple tabs (notebook pages) to show information from other parts of a project.
One of these pages is an overview page that summarizes what is under the other tabs, and I'd like to link the headlines for each section directly to each displayed page. I've currently solved this by using the index of each tab and calling bootstrap's .tab('show') method on the link within the tab:
$(".overview-link").click(function (e) {
e.preventDefault();
var sel = '.nav-tabs a:eq(' + $(this).data('tab-index') + ')';
$(sel).tab('show');
});
This works since I've attached a data-tab-index="<int>" to each header link in my widget code, but it's brittle - if someone adds a tab later, the current indices will be broken. Earlier I relied on the anchor on each tab, but that broke as well (and would probably break if a new notebook page were inserted as well).
Triggering a web client redirect / form link directly works, but I want to show a specific page in the view:
this.do_action({
type: 'ir.actions.act_window',
res_model: 'my.model.name',
res_id: 'my.object.id',
view_mode: 'form',
view_type: 'form',
views: [[false, 'form']],
target: 'current'
});
Is there any way to link / redirect the web client directly to a specific notebook page tab through the do_action method or similar on FormWidget?
If I understood well you want to select the tab from the JavaScript (jQuery) FormWidget taking into account that the id could change if anybody install another module that adds another tab

You can add a class to the page in the xml form view. You can use the id of the element selected by this class name in order to call the right anchor and select the right tab item. This should happen when the page is completely loaded:
<page class="nb_page_to_select">
$('a[href=#' + $('.nb_page_to_select').attr('id') + ']').click()
NOTE: As you have said the following paragrah I assume that you know where to run this instruction. The solution I suggest is independent of the index.

Solution 1
When the page is loaded you can get the tab list DOM object like this:
var tablist = $('ul[role="tablist"]')
And then you can click on the specifict tab, selecing by the text inside the anchor. So you don't depend on the tab index:
tablist.find('a:contains("Other Information")').click()
I think if you have two tabs with the same text does not make any sense, so this should be sufficient.
Solution 2
Even if you want to be more specific you can add a class to the notebook to make sure you are in the correct notebook
<notebook class="nt_to_change">
Now you can use one of this expressions in order to select the tab list
var tablist = $('div.nt_to_change ul.nav-tabs[role="tablist"]')
// or
var tablist = $('div.nt_to_change ul[role="tablist"]')
Solution 3
If the contains selector doesn't convince you because it should be equal you can do this as well to compare and filter
tablist.find('a').filter(function() {
return $.trim($(this).text()) === "Other Information";
}).click();
Where "Other Information" is the string of the notebook page
I didn't tried the solution I'm giving to you, but if it doesn't work at least may be it makes you come up with some idea.
There's a parameter for XML elements named autofocus (for buttons and fields is default_focus and takes 1 or 0 as value). If you add autofocus="autofocus" to a page in XML, this page will be the displayed one when you open the view.
So, you can try to add this through JavaScript, when the user clicks on the respective link -which honestly, I don't know how to achieve that by now-. But you can add a distinctive context parameter to each link in XML, for example context="{'page_to_display': 'page x'}". When you click on the link, I hope these context keys will arrive to your JS method.
If not, you can also modify the fields_view_get method (here I wrote how to do that: Odoo - Hide button for specific user) to check if you get the context you've added to your links and add the autofocus parameter to the respective page.
As you said:
This works since I've attached a data-tab-index="" to each header
link in my widget code, but it's brittle - if someone adds a tab
later, the current indices will be broken.
I assume that your app allow multi-user interaction in realtime, so you have to integrate somewhere in your code, an update part function.
This function will trig if something has changed and cleanout the data to rebuilt the index in order to avoid that the current indices will be broken.

Wicket replacing panel with ajax fails with MarkupNotFoundException

the page markup has
<div wicket:id="stepPanel" />
tag in it and when the page is first loaded it works great that is
add(new MyFirstPanel("stepPanel"));
works fine. But then when I trigger an Ajax event and request redrawing
addOrReplace(new MySecondPanel("stepPanel"));
target.add(MyPage.this);
i get the following error
Last cause: Failed to find markup file associated. MyFirstPanel: [MyFirstPanel [Component id = stepPanel]]
please note that it tries to find the wrong markup (should look for markup for MySecondPanel) and it fails regardless it succedded to do so before!
I instantiate panels using reflection, but could it be a problem here? No exceptions thrown.
Anwser:
Actually it was something else - I have noticed that one of my AjaxSubmitLinks had reference to a form that was no longer placed in a markup... so whatever you do just remember not to leave that reference.
You are adding MyPage after replacing the Panel causing MyPage to re-render.
There is a good example on how to replace panels here.
Yes you can call panels via reflection. I don't clearly know what you are trying to do with event here but if you want you can attach your panel with AjaxSelfUpdatingTimerBehavior and define the duration which will update this component in the given time period.
Hope its useful.

Can I delay loading of some controls on an xPage to after page loaded

is it possible to delay loading of some controls on an xpage?
This is the problem: let's say you have a control that does a fultextsearch and displays the result in a repeat control. this ft search might take a long time and will hold the webpage loading in a waiting state until the search result is ready.
I want my page to load most of the data initally, and some "time consuming" controls should be loaded in to the page as a sperate request after the inital load.
this way the user will immediatly see the webpage, but some of the data on the page will load a little bit later without holding the webpage in a waiting state from the server.
possible?
The downside to using rendered is that all the value bindings will still evaluate, even if the corresponding markup isn't sent to the page. So the trick here is making sure the components don't even exist until you want them to.
Every component has a getChildren() method. This returns a mutable List of components, which has a add() method. This allows you to add components to the page on the fly, either while the page is loading, or later during an event. For the purposes of what you're trying to do, you would want to defer adding the "expensive" components until a subsequent event.
Create an event handler attached directly to the view root (), give it a unique ID (e.g. "loadExpensiveComponentsEvent", set its refresh mode to partial, set a refresh ID to whatever div or panel will contain the search results, and set its event name to an arbitrary event (e.g. "loadExpensiveComponents"). This prevents your event from being triggered by actual user behavior. Set the event's code to SSJS that will inject your components.
Then add a script block () to trigger the event after the page has loaded:
XSP.addOnLoad(function(){
XSP.firePartial(null, "#{id:loadExpensiveComponentsEvent}");
});
Your page will load without the search result components. Once the page has fully loaded, it will trigger the component injection event automatically.
For guidance on how to code the injection event, open the Java file that has been generated from your existing page to see what components need to be injected and what to set their values to.
You can pack them into a panel and set their rendered status to rendered=#{viewScope.pageFullyLoaded}. Then in the onLoad event have a XSP. partialRefresh request where you set viewScope.pageFullyLoaded=true
A little ugly but doable. Now you can wrap that code into your own custom control, so you could have a "lazyGrid", "lazyPanel" etc.
Not sure why I did not think of this before. the dynamic content control in extlib actually solves this problem. the dcc can be triggered onClientLoad both using javascript and ssjs afer the page has loaded.
one problem I am facing now is that I am already using the dcc on my site so I need to put another dcc within my dcc. and this seem to be a bit buggy. I have reported it to the extlib team on openNTF.

How to force the Drupal form to clear previous results

Recently im working on a project and im trying to generate form elements with the help of ajax technology (implementing a form with codes). the situation is that the user should be able to select from a list of options and then due to his select another list of options should be appeared, then due to his/her select from the second sets of options he/she should see the third series of options. now the problem is that when the user tries to change the first option in the first set, the second option will be regenerate but the third one still sticks on the page. I was trying to use the form_sate['rebuild'] = TRUE
but it did not work and all form elements disappeared. can any one help me to see which code should be implemented and where it should be used?
Without any code it's almost impossible to help, except to say check out the examples modules, specifically the ajax_example module.
The basic principle is that you need a <div> container surrounding your 2nd and 3rd select elements, which will be replaced by the #ajax set on the first element. Then you need another container inside that one surrounding only the 3rd select element, which will be replaced by the #ajax set on the 2nd select element.
Hope that helps.
well.. the form page may contains previous values because of $_POST fields variables..
for example if I want to display clear "add" form on POST submit,
I do this tric to clear drupal previous form values via ajax:
<?php
// AJAX POST handler...
....
$my_form = drupal_render(drupal_get_form("the_form", ...));
$errors = form_get_errors();
if (!$errors) {
// re-render clean form, unset your POST fields....
unset($_POST['link_path']);
unset($_POST['link_title']);
unset($_POST['parent']);
unset($_POST['weight']);
$my_form = drupal_render(drupal_get_form("the_form", ...));
}
?>

How to prevent ajax driven form from being submitted twice?

I am taking my first steps with Ajax while working on a Grails application. I am using
<g:form ...>
<g:submitToRemote ... />
</g:form>
in the most simple way and it worked great out of the box (Thanks grails!). The problem is, that the Ajax call needs about 2 seconds to return and update the html (at least on the test system) and during that time, the user can (and actually does quite often) hit the submit button again. At the moment this results in a 2nd call being made that finally ruins the output (an error msg says, that one cannot submit the same data twice).
What is the best way to prevent this?
Thanks in advance for your input!
The best way to handle this is to disable the submit button in your onSubmit() function. Honestly, I don't know why more sites don't do this. I often go the next step and instead of disabling the submit button, I put the submit button in a span tag and replace the contents of the span tag with static text "Please wait..." That way your users get visual feedback they pressed the button and "top men are working on it".
As dj_segfault said you can do that.
If you want to validate this in your controller, take a look in "Handling Duplicate Form Submissions" in the official docs:
http://grails.org/doc/latest/guide/theWebLayer.html#formtokens
